# Complex Simplify

Core to working with algebra problems is the ability to `simplify complex terms`

, and Mathy provides an environment that generates problems with complex terms that require simplification to satisfy the win-conditions.

## Challenge¶

In Complex Simplify the agent must learn to quickly combine coefficients and like variables inside a single complex term

Examples

`1x * 2x^1`

must be simplified to`2x^2`

`7j * y^1 * y^2`

must be simplified to`7j * y^3`

## Win Conditions¶

A problem is considered solved when there are no remaining complex terms in the expression.

### No Complex Terms¶

Terms are considered complex when there's a more concise way they could be expressed.

Examples

`2 * 4x`

is**complex**because it has**multiple coefficients**which could be simplified to`8x`

`4x * y * j^2`

is**not complex**despite being verbose because there is only a**single coefficient**and**no matching variables**

## Example Episode¶

A trained agent learns to combine multiple low-level actions into higher-level ones that `simplify complex terms`

### Input¶

`4a^4 * 5a^4 * 2b^4`

### Steps¶

Step | Text |
---|---|

initial | 4a^4 * 5a^4 * 2b^4 |

constant arithmetic | 20a^4 * a^4 * 2b^4 |

variable multiplication | 20 * a^(4 + 4) * 2b^4 |

constant arithmetic | 20 * a^8 * 2b^4 |

commutative swap | (a^8 * 2b^4) * 20 |

commutative swap | (2b^4 * a^8) * 20 |

commutative swap | 20 * 2b^4 * a^8 |

constant arithmetic | 40b^4 * a^8 |

solution | 40b^4 * a^8 |

### Solution¶

`40b^4 * a^8`
